Gotta ditto Missy's post. Picture this scenario: mom meets some guy WITH a job, who offers to let her and the baby move in - he'll provide shelter, power, cable, water, air conditioning, internet access, and even groceries - and all mom has to do is provide services for him in return. It's a "deal" that gets made thousands of times a day - and becoming a mom tends to change priorities for young women, especially when faced with the question of how to be able to afford to care for their child. Love may be love, but when push comes to shove, love doesn't buy diapers, or formula. Should mom ever take the chance to "move up" to a better situation for herself and the child, and your son doesn't have all his legal I's dotted and T's crossed in the form of court ordered visitation, he could very well find himself in the situation of having ZERO access to his child without a multi-month court process, and potential legal expenses to boot. As an unwed father, he'll have no rights that can be enforced until he goes to court and has those rights spelled out. (And as grandparents, your ability to have access to your grandchild is dependent on dad's rights.)
The flip side to that coin is that married parents enjoy the exact same legal standing regarding their children, in terms of custody, financial responsibility, etc.
So dad really has two choices: marry mom and work the situation as a unified couple, with both sides contributing to the raising of the child in whatever capacities they are able to agree on (one might earn more, while the other spends more time caring for the child, or both might work and do child care equally - whatever works for them, their schedules, their lifestyles, their resources, etc.), or ....don't marry mom, but get rights established ASAP and anticipate a court determining an exact amount dad will be liable for.
You hit the nail on the head right here. Being a single parent at a young age is the #1 predictor for a woman and child to spend a life in poverty. Supportive family is important - as non-supportive family can tear apart even relationships where money or ability to support a child isn't an issue (which it IS here). But the "biggie" will be which direction your son and mom decide to go - getting married gives BOTH sides equal rights and protections, and the ability to make decisions, face challenges, and solve problems among themselves, while not being married means that outside forces such as the courts will be making many decisions FOR him - most importantly how often he gets to see his child, and exactly how much it'll cost in financial terms. Marriage gives the parents control of the situation, each bearing full responsibility, while non-marriage takes away control and gives it to the courts, but with much better outlined "knowns" in terms of visitation and support. Finally, if dad NEITHER marries mom, NOR seeks to have his rights outlined for visitation, he is completely at mom's mercy, whims, hormonal surges, moods, time of the month, etc. when it comes to his child and he needs to be thinking of having enough jobs to keep her happy since he'd effectively have NO chips to play if mom becomes UNhappy, for ANY reason.The odds are against them staying together but hopefully, with supportive family, they will have a better chance.
